PMC3. Work, roll, cut, shape and fire this versatile fine silver .999 clay. This fine silver clay is suitable for torch-firing as well as kiln-firing.
When fired at 1,650° for two hours, PMC3 is one of the strongest fine silver metal clay available. It has a finer, smoother composition that's easy to work with and manipulate.
Embed findings, gems and glass with confidence firing at a low temperature reduces potential heat-damage. Although the resulting metal will be less stronger than kiln firing.
Composition: Metal powder (90%), water and organic binder (10%) Firing temperature:
1,650°F (899°C) for two hours to achieve highest hardness and maximum durability;
or 1,470°F (800°C) for 30 minutes;
or 1,560°F (850°C) for 20 minutes;
or 1,650°F (900°C) for 10 minutes.
Melting point: 960°C (1,762°F) Density after firing: 9.15 S.G. (rolled silver = 10.5 S.G.)
please note: Every variety of PMC® is sold by the metal weight, not the weight that includes the water and binders that burn off during firing. You get every gram of precious metal you pay for from PMC. PMC® has a strong adverse reaction to contact with aluminum. Do not use aluminum tools or allow your PMC to come into contact with any aluminum object.
